Class cudaAccessPolicyWindow

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.cuda.cudart.cudaAccessPolicyWindow

All Implemented Interfaces:

AutoCloseable

@Properties(inherit=cudart.class)
public class cudaAccessPolicyWindow
extends Pointer

Specifies an access policy for a window, a contiguous extent of memory beginning at base_ptr and ending at base_ptr + num_bytes. Partition into many segments and assign segments such that. sum of "hit segments" / window == approx. ratio. sum of "miss segments" / window == approx 1-ratio. Segments and ratio specifications are fitted to the capabilities of the architecture. Accesses in a hit segment apply the hitProp access policy. Accesses in a miss segment apply the missProp access policy.

Constructor Detail

cudaAccessPolicyWindow

public cudaAccessPolicyWindow()

Default native constructor.

cudaAccessPolicyWindow

public cudaAccessPolicyWindow(long size)

Native array allocator. Access with Pointer.position(long).

cudaAccessPolicyWindow

public cudaAccessPolicyWindow(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public cudaAccessPolicyWindow position(long position)

Overrides:

position in class Pointer

getPointer

public cudaAccessPolicyWindow getPointer(long i)

Overrides:

getPointer in class Pointer

base_ptr

public Pointer base_ptr()

Starting address of the access policy window. CUDA driver may align it.

base_ptr

public cudaAccessPolicyWindow base_ptr(Pointer setter)

num_bytes

@Cast(value="size_t")
public long num_bytes()

Size in bytes of the window policy. CUDA driver may restrict the maximum size and alignment.

num_bytes

public cudaAccessPolicyWindow num_bytes(long setter)

hitRatio

public float hitRatio()

hitRatio specifies percentage of lines assigned hitProp, rest are assigned missProp.

hitRatio

public cudaAccessPolicyWindow hitRatio(float setter)

hitProp

@Cast(value="cudaAccessProperty")
public int hitProp()

::CUaccessProperty set for hit.

hitProp

public cudaAccessPolicyWindow hitProp(int setter)

missProp

@Cast(value="cudaAccessProperty")
public int missProp()

::CUaccessProperty set for miss. Must be either NORMAL or STREAMING.

missProp

public cudaAccessPolicyWindow missProp(int setter)
